There is a bag full of 30 different colored and/or patterned balls. How many different three ball combinations can you have if you pull three balls out of the bag?

 

then 

 

in factorial form, what is the total number of possible combinations there are if you draw all the balls out of the bag one at a time.

First one

 

C(30, 3)    = 4060 different combinations

 

 

Second one

 

30 possibilities * 29possibilities * 28 possibilities * ......* 3 * 2 * 1    =   30!
